Question

The structure of a substrate P strongly resembles substrate Q. In an experiment, By mistake P was used instead of Q as a substrate for the enzyme, Q-ase. The results obtained were identical to the results that would have been obtained using substrate Q. Why did substrate P work in place of substrate Q?

Answer 1

Answer;

C) P and Q have similar binding properties

Explanation;

• Enzymes are biological catalysts that speeds up chemical reactions. Substrates are substances that are acted on by an enzyme to form a product.
• An enzyme catalyzed reaction occurs when the substrate binds to the active site of an enzyme to form and enzyme-substrate complex.
• Substrate P and Q are structurally similar which means they are in a position of binding and fitting in the active site of an enzyme. The strong structural similarity means that the binding properties of these two different substrates may be similar.
• Formation of similar products or results when acted upon by an enzyme mean they are similar in terms of their binding properties, and thus the production of similar product.
